SPECIFICATION forming part of Letters Patent No. 684,045, dated October8, 1901.

Application filed October 20, 1900. Serial No. 33,708. (No model.)

To all whom it 77mg concern:

Beit known that I, FRANCIS H. COOK, a resident of Mead, in the county ofSpokane and State of Washington, have invented certain new and usefulImprovements in Impact Water-lVheels; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates toan improved motor, and more particularly to animproved wheel adapted to be operated by water, steam, compressed air,and the like, the object of the invention being to provide a wheel whichwill be extremely simple in construction and which will utilize everyparticle of force of its driving fluid.

A further obj ect is to providea wheel which will have its buckets castintegral therewith and provided with integral means for preventing thespent fluid from interfering withthe force of the power-giving stream.

A further object is to provide an improved nozzle for regulating thesize and power of the stream discharged against the wheel.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view illustrating myimprovements. Fig. 2 is a view in section of the wheel, and Figs. 3, 4c,and 5 are views of details of construction. I

1 1 represent two circular disks provided centrally with alined holes inwhich a shaft is made integral when the disks are cast. Between thedisks 1 and arranged in circular formation is a series of fixed buckets5. Each bucket comprises a plate having a sharp edge at one end. Theinner end of said plate is curved outward and rearward, as shown at 6,and at its curved portion it abuts against the outer end of the nextadjacent bucket, and guide-plates 7 are disposed approximately parallelwith the main portion of buckets 5 and project into the curved ends ofsaid buckets, the outer ends of the guide-plates 7 extending almost tothe'periphery of the disks 1 and considerably beyond the outer ends ofthe buckets.

In constructing my improved wheel the buckets 5 and guide-plates 7 areprovided at their edges with perforations and placed in the molds fordisksl and held therein by removable plugs, and when the molten metal ispoured into the molds it will fill the perforations in the buckets andguides and form the wheel into one integral casting, thus dispensingwith the use of bolts, rivets, &c., which are a source of greatannoyance in all wheels of this character heretofore known.

In operation myimproved wheel is mounted lower edge, although the streammight be forced against the side or top, as desired. When water is usedas a motive power, I provide a nozzle 8, having a series of partitions 9therein, forming a series of outlet-chambers, and a gate or valve 10 ismounted to slide in said nozzle 8 to open or close any number ofcompartments or chambers in the nozzle, thus regulating the size andforce of the stream supplied to the wheel. A suitable rod or stem 10 isprovided on said valve for operating it, and a wire or cable 11 isconnected at its respective ends to the valve and held between its endsin an arm 12 on a roller 13, which latter is mounted on a track 14,provided with springs 15 to hold the track and roller thereon away fromthe nozzle, thus exerting a springpressure on valve 10 to overcome thewaterpressure thereon and permit the ready operation of the valve.

The operation of my improvements is as fol lows: The stream of waterwill first strike the outer end of one guide-plate 7 and be deflectedthereby into the curved forward end of bucket 5 to drive the wheelarouud,.and the spent water will be deflected by the curved end ofbucket 5 in front of guide-plate 7, thus carrying it out of the wayofthe fresh supply, and hence not interfering with the latter, and it willbe seen that the power of the stream is twice utilized, as it will whenit first strikes guide-plates 7 give power to the wheel and again whenit strikes the forward curved ends of the buckets 5, where the flow ofwater is completely reversed.

While I have shown and described my impreferably so as toreceive thestream at its provetnents in connection with astream of water as themotive power, it is evident that steam or compressed air or the likemight be used with equal effectiveness, and hence I do not wish to belimited to the use of water.

Various slight changes might be resorted toin the general form andarrangementof the several parts described without departing from thespirit and scope of my invention, and hence I do not limit myself to theprecise details set forth, but consider myself at liberty to make suchslight changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A wheel employing fluid motive power, comprising a series of fixedbuckets and a support therefor, each of said buckets made U-shaped atone end and having its inner wall extending a considerable distancebeyond the free end of the outer wall and a plate spaced from andapproximately parallel with the long Wall of said bucket and forming anelongated channel open at one end and communicating at its otherend withthe U-shaped portion of the bucket.

2. In a motor, the combination with parallel disks or heads, of a seriesof fixed buckets between said disks or heads, each bucket made U-shapedat one end and havingits inner wall extending a considerable distancebeyond the free end of the outer wall and a plate disposed approximatelyparallel with the long inner wall of the bucket and terminating withinthe space between the two walls forming the U-shaped portion of thebucket, the long inner wall of the bucket and the guide-plate forming anelongated channel for the passage of motive fluid.

3. In a motor, the combination with parallel disks or heads, of anannular series of buckets fixed between said disks or heads, each bucketmade U-shaped at one end and having its inner wall extending aconsiderable distance beyond the outer wall and terminating against theouter face of the outer wall of the adjacent bucket and cooperatingtherewith to form one wall of an elongated channel, and a guide-platedisposed approximately parallel with the long wall of the bucket andterminating at one end in the space between the walls of the bucket andconstituting the other Wall of said elongated channel.

4:. A wheel forem ploying fluid motive power made ina single casting andcomprising a supporting-frame, bucket-s integral with said frame andeach having a U-shaped portion at one end, and plates also integral withsaid frame and spaced from and approximately parallel with said bucketsto form elongated channels or waterways, the forward ends of said platesprojectinginto the U-shaped portions of the buckets.

5. In a motor, a single casting comprising parallel disks, a shaftextending through the center of the disks and made integral therewith,buckets between the disks and integral therewith each bucket having aU-shaped end and guide-plates integral with the disks and projectinginto the U-shaped portion of the buckets and spaced from the walls ofsaid buckets.

G. In a motor, the combination of a wheel having an annular series ofbuckets, a nozzle disposed to discharge fluid into said buckets, saidnozzle having a series of outlet-passages, a slide-valve forsaidoutlet-passages, a springactuated bar parallel to said valve, a roller-to travel on said bar, and a flexible device connected with the Valveand with said roller. In testimony whereof I have signed thisspecification in the presence of two subscribing witnesses.
